MUSIC-LEAF TURNER.

SPECIFICATION forming part of Letters Patent No. 356,983, dated February1, 1887.

Application filed September 22,1886. Serial No. 214,273. (No model.)

To all whom itmay concern: Be it'known that l, PATRICK LYNETT OAR- DEN,of Dixon, Solano county, State of California, have invented anImprovementin Music-Leaf Turners; and I hereby declare the following tobe a full, clear, and exact description of the same.

My invention relates to the class of musicturners; and myinventionconsists in the novel arrangement and construction of the leaf-holdingarms, the operatingkey, the power-transmitting mechanism between the keyand the leaf-holding arms, by which they are successively actuated, theadjustable frame for attaching the device to the rack of the piano andfor holding music of various length,and various details, all of which Ishall hereinafter fully describe.

The object of. my invention is to provide a simple and effectivemusic-leaf turner adapted to be readily attached to the rack of anypiano and to be easily operated.

Referring to the accompanying drawings for a more complete explanationof my invention, Figure l is a perspective view showing the applicationof my music-leaf turner to the rack of a piano. Fig. 2 is a perspectiveview showing the details of the power-transmitting mechanism.

Ais the piano, having the ordinary rack, a.

B is a standard, the lower portion. of which is provided with a foot,I), which rests upon the base of the rack a. Fitted to the face of thestandard is a sliding bar, D, which by its movement adapts the length ofthe standard to any length of music. This bar may be fitted to thestandard in any suitable manner, though I have here shown a set-screw,0?, projecting within a slot, (1, made in the standard. By adjustingthis set-screw the sliding bar may be fixed in the position to which itis adjusted. v

The face of the bar D is grooved, as shown at (1 for the reception ofthe back of the music or musicbook, and on each side of the groove arearranged spring clasps d, for cl an1p .ing the back of said music orbook.

To the top of the sliding bar D is hinged, at c, the arm 0, which passesdown behind the manner. The hinging of the bar and the arm togetherprovides for the ready application of the device to-any rack. Hinged ate to the top of the arm 0 is the box or casing E, the angle of which isregulated by means of the set-screw e, passing through a short bracket,6 on the base of the box and bearing against the arm 0. Within this boxis mounted the shaft F, upon which is secured the gearwheel H.

I is a key let through the base of the rack a, its outer end projectingwithin convenient reach of the player. It is suitably pivoted orfulcrumed, and has loosely connected with its rear end the rod Jr Thisrod extends upwardly,and has pivoted to its upper end within the box arackbar, L, which is held forward to its engagement with the gear-wheelH by means of a spring, Z. A spring, j, around the rod J throws it backagain when the key is relieved. that the rack-bar L must be thrown fromits engagement with the gear H, so as not to reverse it. the box aninclined plane or cam, M. Secured to the back of the box is a strip, N,having made in it a T-shaped groove, n. On the back of the rack-bar L isa stud, Z, with a head. Now, when the rack bar has been moved to theupper limit of its stroke, its upper end coming in contact with theinclined plane or cam M, it is forced back on its pivotal center untilthe head of its stud Z enters the open top of the groove a. The rack-baris thus held away from the gear, and may move down with the rod J underthe influence of the spring j. I

Pivoted in the top of the box are spindles O, the lower ends of whichare provided with pinions 0. With these engage segmental gears f,mounted on the shaft F in different positions, so that their action maybe successive. Connected with the spindles O in any suitable manner, asby simply fittingin sockets therein, are the arms 1?, the ends of whichare provided with the leaf-clamps Q. Thesemay be of anysuitablecharacter adapted to clasp the music-leaves. There may be anydesirable number of said arms.

In thus returning, it is obvious To effect this I have at the top of IThe operation of my music-leaf turner-is as 100 50 rack, and is securedthereto in any suitable follows: As I have heretofore mentioned, thestandard 13, with its sliding bar D and hinged arm 0, maybe adjustedreadily to the rack, as shown in Fig. 1, and the boX E may be thenadjusted to the proper angle by means of the set-screw e. Thesheet-music or the book is then fitted to-the grooved face of theadjustable bar D, and is secured by the springclamps d. It is thenopened out, and one of the clamps Q is secured to each leaf. Then thetime comes for turning the first leaf, the key I is dcpressed,wherebythe rod J is forced up, thereby, through the rack-bar L on its top,effecting the partial rotation of the gear H and the shaft F. The firstof the'segmental gears f is thus caused to engage the pinion 0 of thespindle O, carrying the first arm I, and to partially rotate said sindle,whereby it throws said arm over to the other side, thus turningthe leaf. The movement of the rack-bar L is great enough to carry itsupper end against the cam DLwhereby it is thrown back and held by theengagement of its stud Z with the grooved strip N, and being thus freefrom the gear-wheel II, it moves down to its initial position under theinfluence of the springj, leaving the gear in the position to which ithad been turned, so that at the next operation of the key the secondsegmental gear is ready for its engagement. As each leaf has to beturned the keyis operated as described, and at each operation theengagement of the rack-bar with the gear is broken, so as to leave theshaft ready for a continuance of the operation.

The whole device can be made in such small compass as not be in the wayin any manner. The position of the operating-key, right in front of theoperator, renders its use very convenient, as the motion needed to reachit and the power to operate it are scarcely greater than in operatingthe ordinary keys of the piano. If, however, it be found desirable, therod J, instead of terminating at the base of the rack and being operatedby a key at that point, may pass on down to a suitable treadle below,whereby the turner may be operated by the foot.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is
